Mistral shipped a broad expansion of Mistral Studio on November 5 alongside Mistral Large 4 (Le Chonk), opening Managed Agents and the Python Agents SDK (mistralai-agents) in public preview. Developers define an agent's model, instructions, typed Python tools, MCP servers, skills, secrets and Docker sandbox once, then run the same code locally, on self-hosted workers via agents serve, or fully serverless on Mistral's infrastructure via agents deploy.

Deployed agents execute durably across hours or days, automatically resuming from the last completed step after a crash, with span-level execution traces in Studio, human-in-the-loop or programmatic approval gates, and live steering over a bidirectional session channel. The same release adds a natural-language workflow builder in Vibe, native HTTP connectors in private preview, the mistral apps CLI for scaffolding Studio apps, a managed vector search index and an evaluations SDK.

Deployment choice is the pitch: Mistral cloud, a customer's VPC, on premises or a mix, with private cloud and on-prem deployment slated for late November. Named production customers include ABANCA, Accenture, Alten, BNP Paribas, Capgemini, CMA CGM and TCS; Mistral published no pricing for the new pieces.
